FIG. 6 is a flowchart illustrating an immersive interactive method according to an embodiment of the disclosure. Referring to FIG. 1 and FIG. 6, the immersive multimedia system 100 performs the immersive interactive method of the embodiment. In step S610, the immersive multimedia system 100 displays an image screen on at least one of the wall and the ground through the imaging apparatus 140. In step S620, the immersive multimedia system 100 changes the image screen provided by the imaging apparatus 140 in response to the touch sensing unit of at least one of the plurality of the movable interactive units 120_1-120_N sensing being touched. Therefore, the immersive multimedia system 100 in the embodiment provides an immersive interactive context through the movable interactive units 120_1-120_N and the imaging apparatus 140. Three exemplary embodiments are further presented to illustrate the operating modes provided by the immersive multimedia system 100 of the disclosure.

FIG. 7 is a flowchart illustrating an immersive interactive method according to the first embodiment of the disclosure. FIG. 8A is a schematic view of an immersive interactive context according to the first embodiment of the disclosure. FIG. 8B is a schematic view of another immersive interactive context according to the first embodiment of the disclosure. Referring to FIG. 1, FIG. 7, and FIG. 8A, in step S710, the immersive multimedia system 100 performs the first interactive mode. In step S720, in the first interactive mode, the imaging apparatus 140 displays an image screen on at least one of the wall 701 and the ground 702, such as a forest background image displayed on the wall 701 and the ground 702 in FIG. 8A. In step S730, the computer device 110 controls at least one of the movable interactive units 120_1-120_N to emit audio signals and color lights. The light-emitting units of the movable interactive units 120_1-120_N respectively emit color lights. The speakers of the movable interactive units 120_1-120_N respectively emit audio signals. In step S740, the computer device 110 controls at least part of the movable interactive units 120_1-120_N respectively to move randomly on at least one of the wall 701 and the ground 702.

In step S750, the computer device 110 determines whether the touch sensing unit of at least one of the plurality of the movable interactive units 120_1-120_N senses being touched. For example, when the movable interactive unit 120_1 emits a bug sound through a speaker, according to the bug sound and the image of the bug sound, the user 801, for example, searches for the movable interactive unit 120_1 to touch the movable interactive unit 120_1. In step S760, when the touch sensing unit of the movable interactive unit 120_1 senses being touched, the computer device 110 stops moving the movable interactive unit 120_1 touched. In step S770, the computer device 110 displays a specific pattern at a position on the wall 701 and the ground 702 corresponding to the movable interactive units 120_1-120_3 touched through the imaging apparatus 140. In this regard, specific patterns are icons such as insects, birds, puppies, or other animal icons. When the user 801 successfully touches the movable interactive units 120_1-120_3, the icons are displayed on the movable interactive units 120_1-120_3.

Referring to FIG. 1 and FIG. 8B, the first interactive mode also provides an effect of multiplayer interactive games. As shown in FIG. 8B, according to steps S710 to S770 in FIG. 7, the computer device 110 controls at least one of the movable interactive units 120_2-120_N to emit audio signals and color lights. For example, the users 802 and 803 may compete to search for the movable interactive units 120_2-120_4 according to images and sounds, such as insect calls, bird calls, or frog calls to touch the movable interactive units 120_2-120_4. Moreover, when the touch sensing units of the movable interactive units 120_2-120_4 sense being touched, the computer device 110 stops moving the movable interactive units 120_2-120_4 touched. The computer device 110 displays specific patterns at positions on the wall 701 and the ground 702 corresponding to the movable interactive units 120_1-120_3 touched through the imaging apparatus 140. In this regard, specific patterns are icons such as insects, birds, frogs, or other animal icons. Therefore, the first interactive mode in the embodiment is capable of providing one or more people with interactive training or games and thereby offering a good user immersive interactive experience.

FIG. 8C is a schematic view of the height sensing of a movable interactive unit according to the first embodiment of the disclosure. FIG. 8D is a schematic view of the position sensing of a movable interactive unit according to the first embodiment of the disclosure. Referring to FIG. 8C, the movable interactive units 820_1-820_3 perform sensing, for example, through an infrared sensor and provide the sensing information to the computer device, so that the computer device adjusts the height distribution of the movable interactive units 820_1-820_3 according to the calculated height of the user 801. For example, the computer device adjusts the maximum height of the vertical range of the movements of the movable interactive units 820_1-820_3 according to the maximum height the user 801 touches. Referring to FIG. 8D the movable interactive units 820_4 to 820_5 perform sensing, for example, through an infrared sensor and provide sensing information to the computer device 110, so that the computer device 110 adjusts the horizontal distribution of the movable interactive units 820_1-820_3 according to the calculated range of the movement of the user 801. For example, the computer device adjusts the horizontal range of the movement of the movable interactive units 820_1-820_3 to be close to the user 801 so that the user 801 may approach to touch them. Therefore, each of the movable interactive units in the modes in FIG. 8A and FIG. 8B is capable of performing the sensing operation as shown in FIG. 8C and FIG. 8D to provide better interaction.

FIG. 9 is a flowchart illustrating an immersive interactive method according to the second embodiment of the disclosure. FIG. 10A is a schematic view of an immersive interactive context according to the second embodiment of the disclosure. FIG. 10B is a schematic view of another immersive interactive context according to the second embodiment of the disclosure. Referring to FIG. 1, FIG. 9, and FIG. 10A, in step S910, the immersive multimedia system 100 performs the second interactive mode. In the second interactive mode, the imaging apparatus 140 displays an image screen on at least one of the wall 901 and the ground 902, such as a Grand Canyon background image displayed on the wall 901 and the ground 902 in FIG. 10A. In step S920, when the touch sensing unit of at least one (e.g., the movable interactive unit 120_3) of the plurality of the movable interactive units 120_1-120_N on the wall 901 and the ground 902 senses being touched by the touch object (e.g., the hand of the user 1001), the computer device 110 controls the movable interactive unit 120_3 touched to move to follow the touch object. In step S930, the computer device 110 emits various color lights through the light-emitting unit of the movable interactive unit 120_3 touched and the light-emitting unit of at least one of part of the plurality of the movable interactive units untouched. In step S940, the computer device 110 controls at least one of part of the plurality of the movable interactive units untouched to move toward the movable interactive unit 120_3 touched. In step S950, the computer device 110 determines whether at least one of part of the plurality of the movable interactive units untouched touches the movable interactive unit 120_3 touched. If not, the computer device 110 continues to perform step S940. If yes, in step S960, the computer device 110 stops moving the movable interactive unit 120_3 touched.

For example, the imaging apparatus 140 may display a specific pattern, such as a bird icon, on the movable interactive unit 120_4. Moreover, when the user 1001 touches the movable interactive unit 120_3, the movable interactive unit 120_4 moves toward the movable interactive unit 120_3, and the bird icon follows the movable interactive unit 120_4 to move. In this regard, the user may try to prevent the movable interactive unit 120_3 from being touched by the movable interactive unit 120_4. In this way, the hand of the user 1001 is in front of the movable interactive unit 120_3, so that the infrared sensor of the movable interactive unit 120_3 senses the displacement of the hand of the user 1001, and thereby the computer device 110 controls the movable interactive unit 120_3 to perform corresponding displacement.

Referring to FIG. 1 and FIG. 10B, the second interactive mode also provides an effect of multiplayer interactive games. As shown in FIG. 10B, according to steps S910 to S960 in FIG. 9, the computer device 110 controls at least one of the movable interactive units 120_2-120_4 to emit audio signals and color lights. The arrangement of the reference numerals of the movable interactive units is for illustration only. Users 1002 and 1003 may have a competition. For example, after the users 1002 and 1003 respectively touch the movable interactive units 120_1 and 120_3, an eagle pattern or other movable interactive units displayed on the wall 901 by the imaging apparatus 140 move toward the movable interactive units 120_1 and 120_3; and the users 1002 and 1003 may compete for not being touched by the eagle pattern or other movable interactive units. Therefore, the second interactive mode in the embodiment is capable of providing one or more people with interactive training or games and thereby offering a good user immersive interactive experience.

FIG. 10C to FIG. 10E are schematic views illustrating the detection of a touch object according to the second embodiment of the disclosure. Referring to FIG. 10A and FIG. 10C to FIG. 10E, in the embodiment, the camera unit (e.g., the camera unit 450 in FIG. 4) of the movable interactive unit 120_3 is disposed on the casing of the movable interactive unit 120_3. Moreover, in the second interactive mode, the camera unit of the movable interactive unit 120_3 touched is adapted to photograph a touch object 1004 (e.g., the hand of a user); the movable interactive unit 120_3 touched determines the moving direction of the touch object 1004 according to a plurality of brightness value changes of a plurality of regions 1010-1018 in the camera image obtained by the camera unit; and the movable interactive unit 120_3 touched moves accordingly according to the moving direction.

As shown in FIG. 10C, the camera unit of the movable interactive unit 120_3 photographs the image of the plurality of the regions 1010-1018 of the touch object 1004. The regions 1010-1018 in the image have the same or similar brightness values. At the next timing, when the touch object 1004 moves, as shown in FIG. 10D, the camera unit of the movable interactive unit 120_3 photographs the image of the plurality of the regions 1010-1018 of the touch object 1004, and the regions 1010, 1013, and 1016 in the image are changed to have brightness values that are different from or greater than those of the regions 1011, 1012, 1014, 1015, 1017, and 1018. In this regard, the computer device 110 determines, for example, that the touch object 1004 moves to the left, so the touch object 1004 controls the movable interactive unit 120_3 to also move to the left. Therefore, at another next timing, when the movable interactive unit 120_3 moves corresponding to the touch object 1004, as shown in FIG. 10E, the camera unit of the movable interactive unit 120_3 photographs the image of the plurality of the regions 1010-1018 of the touch object 1004. The regions 1010-1018 in the image are restored to have the same or similar brightness values.

FIG. 11 is a flowchart illustrating an immersive interactive method according to the third embodiment of the disclosure. FIG. 12A is a schematic view of an immersive interactive context according to the third embodiment of the disclosure. FIG. 12B is a schematic view of another immersive interactive context according to the third embodiment of the disclosure. Referring to FIG. 1, FIG. 11, and FIG. 12A, in step S1110, the immersive multimedia system 100 performs the third interactive mode. In the third interactive mode, the imaging apparatus 140 displays an image screen on at least one of the wall 1101 and the ground 1102, such as a specific game background image displayed on the wall 1101 and the ground 1102 in FIG. 11A. In step S1120, the computer device 110 controls the movable interactive units 120_1-120_N to move, the first part of the movable interactive units 120_1-120_N are disposed on the wall 1101, and the second part of the movable interactive units 120_1-120_N are disposed on the ground 1102.

In step S1130, a target color light is emitted through the first sub-part of the first part of the movable interactive units and a mixed color light is emitted through the second sub-part of the first part of the movable interactive units. In step S1140, the computer device 110 controls the second part of the movable interactive units 120_1-120_N respectively to emit monochromatic lights of different colors and controls the second part of the movable interactive units 120_1-120_N respectively to move randomly on the ground 1102. In step S1150, when the touch sensing unit of at least one movable interactive unit in the second part of the movable interactive units 120_1-120_N senses being touched, according to the color lights emitted by the touch sensing unit touched in the second part of the movable interactive units 120_1-120_N, the computer device 110 mixes and determines the mixed color lights and stops moving the movable interactive unit touched.

For example, the first part of the movable interactive units 120_1-120_N are arranged to form a specific array 121 and remain stationary, and the imaging apparatus 140 displays a target color around the specific array 121. When the users 1201, 1202, and 1203 have a game together and touch the movable interactive units 120_1-120_3 in the second part of the movable interactive units 120_1-120_N, the computer device 110 performs color mixing according to the first color light, the second color light, and the third color light respectively emitted by the movable interactive units 120_1-120_3, so that the first part of the movable interactive units 120_1-120_N in the specific array 121 emit mixed color lights. In other words, the user 1201, 1202, and 1203 determine whether the color mixing result displayed by the movable interactive unit in the specific array 121 is the same as the target color displayed around the specific array 121 to determine whether to touch other movable interactive units so that the color mixing result displayed by the movable interactive units in the specific array 121 is the same as the target color displayed around the specific array 121. Therefore, in step S1160, the computer device 110 determines whether the mixed color light and the target color light are the same. If not, the computer device 110 re-performs step S1150. If yes, the computer device 110 performs step S1170. In step S1170, the computer device 110 displays a specific pattern or a specific text in the image screen through the imaging apparatus 140.

Referring to FIG. 1 and FIG. 12B, the third interactive mode provides an effect of multiplayer interactive games.
